AWNING.

Application filed August 27, 1924. Serial No. 734,483.

The invention has for an object to effect improvement in combination shade and awn-' and to improving the function thereof in important respects. It is an important aim to obviate the extension of the shade and awning webbing slidably under the guide rod or retainer, against which the material must rub, in the operation of the device, while at the same time permitting all desired degrees of adjustment of the device, to vary the heightof the lower part of the shade above the window sill,or to vary the adjustment of the upper part of the device with respect to he lintel of the window alternatively or to gether. That is to say, I provide such con struction that the lower part of the shade.

awning element may be extended to its fullest. while the upper part may be lowered to various degrees to provide an opening for admission of light or air at the upper part of the window; or the upper part may be lowered first and the lower part elevated in varied relation, or the upper part may be kept extended to the upper part of the window while the lower part is adjusted to various positions.

. t is tiat all of these functions are accomplished without abrasive contact of any structural elements with the fabric of the shade awning, and by manipulations which are quite simple and are adapted to be accomplished by women and children without difliculty.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts as may be I lowing description and the accompanying drawings, in which,

Figure 1 is a perspective exterior view of av window equipped with my invention, the shade-awning being fully extended both at the top and the bottom, two adjustments of the lower part upwardly being indicated in dotted lines at A and B respectively.

important advantage of the invention.

more fully understood from the fol- Figure 5 is a front elevation of the Window with my device in released or fully retracted position. I

Fig. 6 is a detail longitudinal section of a construction of the roller.

There is illustrated a window opening having a usual window frame 20 therein, in which there are slidably mount-ed upper and lower sash 21 and 22 respectively, as shown in Figure 2. Mounted in guides 23 on the frame 20 at each side (as shown in Figures 1, 2 and 5) there is a spring roller24, which may be constructed as shown in Fig. 5, its mounting beingsuch that the roller moves vertically in the window but with the roller key held suitably against rotation. The construction may include any familiar form including dogs, whichare operative to positively hold the roller against winding action except when operating in the familiar way for winding, but in the embodiment particularly illustrated, it is possible (and has been my practice) to omit such dogs, and leave the roller under tension tending to wind at all times except when held against such action by the respective operating, or draft, cords and webbing, presently to be described.

There is attached to the roller webbing material to suit the purposes, extended in opposite directions when in use, forming a shade section 25 at the upper part, and an awning section 26 at the lower part, arranged in such fashion as to be wound simultaneously when the roller operates and being of substantially the same length, so that when one section is fully wound on the roller, so will the other be. The shade section 25 has an operating cord 27 attached thereto extended upwardly and over a pulley 28 located centrally on the lintel of the frame 20, then downwardlyand under a catch pulley or other device for holding the cord positively in adjusted positions a 29, on the sill of the window. An awning how 30 is pivoted in the usual brackets 31 at the sides of the frame, the lower end edge of the awning section 26 being attached thereto, and an operating cord 32 is connected to the bow extended downwardly therefrom and under a catch pulley or other securing device I 33, on the sill of. the window. By this construction, it will be seen. that when it is desired to close the upper part of the window only without extendingthe shade section 26 outwardly from the windowfraine, it is only necessary to release thecor'd 32,.ivhich permits the bow to move upwardly to the position shown in Figure 15, while the cord 27 is operated. Under such operation the roller will move upwardly as indicated by the arrow there adjacent in Figure 2 until it.

reaches a position midway bet-ween the bow and the upper edge of the shade section 25, as will be understood. The bow may be secured also at intermediate positions, as at a and Z), Figure 2. Should it be desired to keep the awning extended at the lower part and to lower the shade section from the top besides, the cord 32 is kept secured to the fastener 33 with the bow in fully lowered position, while the cord 27 is released and the shade section 25 permitted to lower.

Similarly, the shade section 25 and the awning section 26 may both be permitted to retract as desired, to admit Whateverproportion of light at the two parts of the window may best suit the operator. When it is desired to entirely retract the shade-awning, both cords 27 and 32 are released, and the device will then automatically position itself as shown in Figure 5.

In order for this device to operate with satisfaction it is desirable that a minimum of friction shall be developed in the movement of the shade-roller in its guide, and therefore I have evolved, a specially suitable guide device, one form of which is shown in Figures 3 and l. This includes the tubular guide rail 23, before mentioned, having a longitudinal slot throughout its length at the inner side when mounted upon the window frame. The roller key 35 is engaged in a body plate 36 suitably slotted to snugly receive the key, this plate having pins 37 at each end extended outwardly and having revoluble balls 38 thereon of a size to fit loosely in the guide 23.

' The pins 37 are formed with conical heads 39 by which the balls are retained, although other securing means may be utilized. The guide 33 is formed with countersunk apertures at suitable distances, receiving screws 40 by which the guide is secured to the win dow frame, and for further security and rigidity in the guide 33, saddle blocks 4:1 may be interposed between the frame and guide, as required. I

In order to insure the proper functioning of such device as disclosed, especially in the proper functioning of the guide devices I have evolved a double spring roller, in which the ordinary spring is duplicated and mounted in the opposite end of the roller, except that one spring is formed with its helices wound the reverse of those in the other spring, so that the springs may be wound by turnin simultaneously the keys connected to their outer ends in the same direction.

This feature is presented in Figure 6, where a roller body is shown formed in two sections --7 0-7 1- end to end, the major part one of which is bored as at 72, so as to receive I a tenon 7 3 formed on the other. The tenon may be much shorter than the bore 72, the tenon having a transverse opening 74 therethrough, while the bored part is formed with two longitudinal series of openings 75,

alined in pairs so that in case it is necessary to, shorten the roller, the inner end of the bored section only may be cutoff, the tennon of the other section inserted, and a pin 76 driven through alined openings 74 to retain the sections connected and hold them against relative rotation. The parts may be cemented when fitted, for further security. In the outer end of each section a spring 77 is engaged in the manner usual in such rollers, one wound to the right and the other to the left in manufacture, and their outer ends are engaged with respective identical keys 35 mounted revolubly in the extremities of the rollers after any approved method.

I claim 1. An awning device consisting of two parallel vertical lateral guide devices, a spring roller including a roller spring and connected key ten-ding at all times to rotate in the roller, said roller being slidably mounted in the guide devices, the mounting including means to hold the key against r0- tation, webbing attached to the roller and arranged to extend above and below the roller, means to draw the onepart of the web upwardly and secure it in raised positions, and means to draw the other part of the'webbing downward and secure it in various extended positions, including a bow having the webbing connected to an intermediate transverse part, and a pivotal mounting for the how.

2. An awning, an awning cover adapted to be secured at its one end to the window frame, a roller, a cover secure-d intermediate its length to said roller, a bow, the'other end of said awning secured to said how; and guides adapted to be secured to the window frame, the ends of said roller being in sliding engageinent with said guides. I

3. In an awning including a frame, a bow pivoted on the exterior of the frame, a spring.

roller, and a webbing having a medial portion attached to the roller and its ends connected to the bow and top of the frame respectively; the combination therewith of vertical guides the roller adapted to be slidably mounted in said guides and its mounting including a key rotatable in the roller fixed against rotation with respect to the guides and a spring under tension between the key and roller tending at all times to rotate the roller, a manually extensible connection between the lower part of the frame and adjacent end of the webbing, and a manually extensible connection between the top of the frame and upper end of the webbing.

In testimony whereof I aflix my signature.
